INCINERATOR APPLIANCE FOR HEATING UNITS Filed March 14 1931 5 Sheets-Sheet 3 KENNETH .Z 755//\/ Patented Apr. 25, 1933 UNITED STATES KENNETH J. TOBIN, OF CHICAGO, ILLINOIS INCINEBATOR APPLIANCE FOR HEATING UNITS Application filed March 14, 1831.

This invention relates generally to incinerator devices for the burning or cremation of refuse and concerns itself with such de; vices and their application to heating units.

a It is an object of this invention to provide an incinerator appliance which shall be capable of completely cremating refuse, including garbage of all kinds, in substantially less time than is required by known incinerators.

It is a further object to provide an incinerator appliance capable of quick and easy installation in a heating unit by unskilled labor and which utilizes kin its operation the fuel supply of such unit.

An object also is the provision of an incinerator device for use more particularly with liquid or gas fired heating units and which shall not require any greater expenditure of fuel than is required to heat the home or other, place where such unit is utilized.

A further object is the provision of an incinerator device so constructed and ar- 26 ranged relative to the heating unit that the residue of the refuse after cremation is disposed of through the flue of such unit.

A further object of the, invention is the provision 'of an incinerator appliance for I no heating units which may also serve as a refuse rece tacle.

Other ob ects as well as advantages of the invention will become apparent from the following description and drawings forming as part of the spec1fication.,:

Referring to the drawings the numeral 10 indicates as a whole a heating unit pro- 5 videdwith the customary water jacket 11 and a combustion chamber or fire pot 12. It is to be understood that the particular unit disclosed is shown for the purpose of illustration only, it being clear that the invention may be utilized with other types of heating units. Furthermore, the particular unit illustrated is of the oil burning type. It is to be understood here also that the invention, while particularly adapted to heating units employing a fluid fuel supply is not to be limited to such heating units. An oil burner 13 is mounted in the bottom of the heating unit and furnishes the heat supply therefor.

Mounted in the combustion chamber or fire pot 12 is a supporting member or bracket 14. This bracket embodies essentially a plurality of spaced vertically positioned angle members 15 provided at their upper margins with horizontally extended flan cs 16 for a purpose hereinafter disclosed. gecured, preferably by welding, to the lower portions of the member 15 are horizontally extending angle members 17. It is to be noted that the vertically positioned flanges of each of these angle members lie in the same plane. Cross pieces 18 and 19 are secured to the vertical angles and to the horizontal angles, respectively, in order to maintain them in roper spaced relationship. The horizontal anges 16 of thebracket construction" are adapted to be positioned on the combustion chamber or fire pot to support one end of the bracket therefrom. A door opening is formed in what may be termed the front of the heating unit. This opening is adapted to be closed by means of a door 21. The end of the bracket opposite from that provided with the sustaining' flanges 16 is adapted to be seated in this opening and to be supported therein.

The supporting bracket is adapted to carry a refuse receptacle 22. It should be observed that this receptacle is of such extent that the door 21 adapted to close the door opening 20 formed in the heating unit serves also to close the open front end 23 said receptacle. With the exception of this opening the receptacle constitutes es sentia-lly a closed structure. An opening 24 is provided in the bottom of the receptacle adjacent the forward end thereof. Extending from this opening is a tubular member 25, this member beingadapted to trap a portion of the flame from the burner 13 and direct such flame into the receptacle. In the top of the receptacle and offset from the opening in the bottom thereof another opening 26 is provided. This latter open- 7"- reoeptacle within the heating unit at all times. Such receptacle is capable of being utilized as a refuse receiver as well as an appliance in an incinerator structure. For this purpose a stand 27, positioned in front of the heating unit may be utilized. The

' top of 'the stand as clearly shown in Figure 5 is preferably in alignment with the lower portion of the opening in the heating unit. It becomes, consequently, a simple matter to withdraw the receptacle from the heating unit and position it upon the stand which, if desired, may be supplied with rollers (not shown) for this purpose, and refuse may be collected therein until such time as it is desired to cremate the same.

In Figures 6 to 9, inclusive, there is disclosed a modification of the su porting bracket and refuse receptacle. In this modification the tubular member is eliminated and in its stead a series of openings 30 is provided adjacent the forward end of the receptacle 31. In order to prevent outward movement of the bracket member 32 a tongue 33 is struck downwardly from each horizontal leg 34 of the horizontal angle members 35 of the bracket member.

his tongue is adapted to have engagement with the combustion chamber or fire pot as clearly shown in Figure 5 of the drawings, for the purpose of preventing movement of the bracket member within theopening. The rece tacle 31 is provided with a rear wall 36 w ich is inclined upwardly from the bottom thereof and which is provided with a fillet 37 between the bottom and rear wall for a purpose hereinafter indicated.

It may be found inconvenient, in View of differences in heating unit constructions, to mount a supporting bracket in said unit in the manner hereinbefore indicated. To provide for such a contingency the construction shown in' Figures 10 and 11 has been designed. The supporting bracket 40 illustrated in these figures is constructed of a plurality of T-shaped sections which are spaced apart and maintained in such relation by means of a plurality of cross pieces 41. These T-shaped sections are formed to provide a horizontal portion 42 constituting inwardly directed webs 43 and oppositely extending flanges 44 and. 45. It is observed that the upwardly extending flange 44 terminates at a oint where the bracket member is provi ed with vertically extending legs 46 for the purpose of permitting ready formation of such legs. These legs in turn are provided with foot portions 47 in order to properly position the bracket member within the combustion chamber. The web portions 43, as clearly shown in Figure 10 of the drawings, extend into the door opening where they are supported. Down-struck tongues 48 are provided in each of said web portions for the purpose of preventing outward displacement of said bracket member.

It is apparent from the foregoing that the structure of this invention clearly attains all of the objects set forth. It is evident that with a heating unit utilizing a fluid heat supply, an incinerator which, in its operation, utilizes such fuel supply is a necessity if refuse is to be disposed of in this manner. No'additional expense for a heat supply is necessary. Moreover, the burner o t 1e heating unit is not required to operate for a greater length of time because of the incinerator attachment than is necessary to the desired heating of the home or other place where such unit may be installed. The incinerator construction embodying the refuse receptacle and the heat source of the heating unit is very effective in rapidly reducing all refuse of whatever nature to a substantially powder form in view of the intense heat within the com- 1 bustion chamber or fire pot. Moreover, this heat even after the burner has been shut off, is effective in removing a substantial port-ion of the moisture content of the refuse. It has been proven by actual test that whole citrus fruits have been decomposed within fifty (50) minutes from the time they were inserted in the refuse receptacle. It should be noted that citrus fruit rinds are utilized in testing effectiveness of an incinerator.

/ viii) Moreover, because of the alignment of the opening in the top of the receptacle with the flue of the heating unit has been found by actual experiment that the powder resulting from the decomposition of the refuse in the receptacle has been blown out through the line by means of the draft created in the fire pot. To aid in this disposal of the refuse powder the construction of the receptacle shown in Figure 6 of the drawings embodying the fillet 37 and the inclined rear wall 36 has been adopted. The incinerator device may be readily installed in existing heating units and may be utilized with gas or oil burning heaters of any known make. In the summer time when heating of a home is not necessary or desirable the incinerator may still be effectively utilized. For this purpose the heat source of the heating unit may be employed. The heat from such source, while used for the decomposition of the refuse, is effective at the same time to heat a water supply to provide hot water for washing and bathing urposes. It is not necessary to utilize the heat source to such an extent that the house is heated. It is also apparent that the receptacle of the incinerator construction may serve as well as a simple refuse receptacle.

it is apparent that numerous changes and modifications in the details of construction may be resorted to without departing from the spirit of this invention. It is to be understood, therefore, that all such changes and modifications are deemed to be comprehended within this invention which is to be limited only by the scope of the claims appended hereto.
